I don't understand how Nvidia didn't up their texture address and filtering when they reworked their SP with GT200. The old G92 cores had 8 texture address/filter for every 16SP but GT200 has 8 texture address/filter for every 24SP. Those textures did a whole lot more for games than just higher SP clocks with G92 with modern games.

Alot of that I really didnt understand but I agree with the GTX 200's not living up to the price! I'm disappointed in Nvidia for flooding the market with GPUs that for one arent that much faster than previous gen GPUs and two are way expensive.

You know... Come to think of it... I think we should boycott Nvidia! --------------- EVGA 780i--Intel E8400@4.05Ghz--TRUE--EVGA 8800GT SLI--2X2GB OCZ reaper @800mhz 4-4-4-15-1T--Antec 900--PCPC 750 silencer--150 raptorX! |

Agreed,i say NVIDIA must do something like the 8800 series, remember them?

Even Crysis doesn't need that much processing power if you look at any of the reviews. A 260gtx is whole 3-5 fps faster than 9800gtx with much lower memory bandwidth and whole lot less ROP. In the situation of Geforce 7 and 8 it was a time when we needed more processing power than Geforce 7 can dish out. But those days have past and gone where Geforce 8 have enough processing power. Fact is fillrate is king combined with right amount of memory bandwidth.

TY Marv, I digested most of it, then reread it again and got the rest. The advantage nVidia had over ATI has been lessened by ....nVidia. So, youre saying future games will require higher pixel rates. Could this be so forward looking that the newer DX model will make texturing that much easier? And like ATI who did the shader AA thing, nVidia is doing the pixel/process thing? --------------- Every artist is a cannibal,every poet is a thief,they all kill their inspiration then sing about their grief |

For instant gratification you need more texture fillrate with right combination of bandwidth which GT200 doesn't deliver that much more than G92. Not more SP. The bandwidth bottleneck is gone for the most part. Nvidia want maximum performance in DX10 & future games. This will require more shading power than G80's ratio would provide. In these kinds of games, GT200 performs well and the increase in per clock performance compared to G80 is close to the increase in ALU performance per clock.
This is what Nvidia is aiming for 260gtx beating out gx2 but that's really upto the developers not Nvidia but what Nvidia got is slightly better performance than a single 9800gtx in most of the current titles out. Just some ridiculous bandwidth starved situations does GT200 prevail. Do you see what ATI was aiming at the time when they made 2900xt? Nvidia is just following suit and is just catching up in that dept.

Couldnt this also mean a lean (maybe too far) for thier gpgpu direction? leaving game capabilties on the lower side. And if so, this could be easily rectified in the refresh?

With CUDA coming to light and this overcompensation of processing power in the new GPUs....it looks like NV has a master plan brewing... |

With a refresh Nvidia needs to up the texture ratio by 2x folds. Then the instant gratification of performance for old or new just like how 8800gt was able to beat down G80GTS with less memory bandwidth and rop. More shader is longevity and the future but not present time. If you see my review about my 8800gs I talk about texture fillrate compared to 9600gt. It's true that more SP does help in these low end cards to a certain extent but that performance had much to do with having more texture fillrate compared to 9600gt while having less rop and less memory bandwidth and still comparable performance.

Doesnt it make more sense for GPU engineers/manufactures to develop the cards around bad a$% games rather than game developers to develop games for the GPU? --------------- EVGA 780i--Intel E8400@4.05Ghz--TRUE--EVGA 8800GT SLI--2X2GB OCZ reaper @800mhz 4-4-4-15-1T--Antec 900--PCPC 750 silencer--150 raptorX! |

The original DX10 was modified by M$ for nVidas sake. This was a exception, not the rule. Looks like I need to read up on DX11. Any sources? --------------- Every artist is a cannibal,every poet is a thief,they all kill their inspiration then sing about their grief |
